Is this the:
integer-part (unit character) fractional-part
notation like calling 9600 baud 9k6?

I like that notation.  Given that it implies the
common engineering notation of only using scientific
notation where the exponent is a multiple of three,
it works well with other 'accepted practices'. :)

I think my first proto will use an LM317 that I
found in my parts box, but later ones will probably
use a Silicon Standards SS6734 series part.  These
guys make a bunch of 300mA LDO regulators that also
come in TO-92 cases.  Yeah.

Speaking of that, whoever makes the next batch of
proto boards might think to use a dual output switching
design that takes in 5-12V or so an produces the 3.3V
and 1.8V outputs.  I'd be glad to help with the design.

Oh, further off topic (but still on topic...) does anyone
have any proto boards made up or will they in the near
furture?  I could use a few.  Contact me off list, please
and we'll try to work something out.  It would be nice
if we could offer something like Leon's board to people.

Oh, and the callsign here is N0YMV. :)

Cheers,
David
